Depends. Not always "smaller blocks waste less space". It depends on the
mix of filesizes. If most files are big, then no.

Consider, for instance, that in a filesystem with a fixed number of
inodes (like ext2/3/4), when using small blocks the structures that list
the blocks are larger, simply because there are more blocks.
